T wlbwhom it may concern):

Be it known thatLEMIL SUTHERLAND, a citizen'of-the United States, residing at Los Angeles, in the county of Los Angeles "and State "of- California, have invented new and useful Improvenientsin'Lawn- Sprinklers, of which the'following is a specification.

The object of my invention is-to provide av lawn-sprinkler which. will automatically change the position of the nozzle ofthe sprinkler from time to time, so that the water willbesprinkled over a large area of lawn,'and

which will automatically "shut off "the water when the area is sprinkled. I accomplish this object by the mechanism described herein and Figure 1 is a perspective View of the upper.

part of the machine with some of the parts broken away for clearness" of illustration.

' Fig. 2 is a side elevation of the upper portion "of the frame and of the turning mechanism viewed from the side opposite that shown in Fig. 1 with the nozzle shown in a different position. Fig. 3 is an end view of the frame and turnlng mechanism in the position shown in Fig. 2 and with a portion of the release g with the sprinkling-nozzle shown in section 1 and the delivery-nozzle omitted.

" In the drawings, A is the base of the frame, to which are secured the standards B. These 4 standards are braced by bars C, secured there R ;to and to the base. 'The standards are secured 'f together at the bottom and center thereof by "the'bindin'g-rods D. Revolublymounted in the top of the standard is the supporting-bar 'E, to the center of which is secured the elbow F, to which elbow the hose Gris secured. This hose passes through a supporting-hook, H secured near the top of the standard, so as to retain the hose parallel with the supporting-bar,

as shown in Fig. 2. The other end'of the hose "is secured to a self-closing hydrant '1, whose operating-handles J andJ are held together by'lOcking-lver K to keep the hydrant open. This lever is pivoted to handle J and has a notch K in its outer end, which passes over the end'of handle J to keep the hydrant open,

as shown in Fig.4. On the opposite side of the supporting-bar from the hose and revolubly secured to'elb'ow F is delivery-nozzle L, whose outer end projects within the sprinkling-nozzle M, as shown most clearlyin Fig. 1. This sprinkling-nozzle is provided with channels 'N and N, the outer ends of'which curve away from each other and away from the central line of discharge from the deliverynozzle, so that when in the position shown in Fig. 1 the discharge of the water from the delivery-nozzle into the sprinkling-nozzle will cause the travel of the sprinkling-nozzle and the discharge end of the delivery-nozzle to the left, and when the sprinkling-nozzle is shifted,

so that the water may pass into channel N, the discharge of water therethrough will cause the sprinkling-nozzle and the free end of the delivery-nozzle to travel toward the right. In

order to provide a greater distribution of water anceweightP, and on the other end is pivotally mounted the sprinkling-nozzle. (Best shown in Fig. 3.) This end of the rod 0, I will designate as the upper end and the end "carrying the counterbalance-weight as the lower end of the rod; Between the supporting-bar andthe outer end thereof is pivoted thereto the shifting lever Q, the outer end of which passes through a plate R, secured to the sprinkling-nozzle. The inner end of the shifting lever moves along the stop-bar S, which is provided with stopsT, slidably mounted thereon and secured in any desired position thereon by thumb-screws T, which .dogs.

stops engage the inner end of the shifting le- Ver to limit its movement.

In the operation of my device, the hose being connected thereto and to the hydrant with the hydrant'locked open, as shown in Fig. 4, and assuming the parts to be in the position shown in Fig. 1, the discharge of the water through the sprinkling-nozzle will cause its travel to the left until the lower end of the,

shifting lever contacts with the stop on the left-hand side of the stop-bar. The momentum of the parts and the-force of the water will cause the free end of the delivery-nozzle to travel still farther to the left; but the travel of the inner end of the shifting lever having been stopped it will cause the inner end of the sprinkling-nozzle to shift its position, so that the water from the delivery-nozzle will now be discharged into channel N, thereby causing the sprinkling-nozzle and the free end of the delivery-nozzle to travel to the right until the inner end of the shifting lever contacts with the stop on the right-hand side of the stop-bar, when the inner end of the sprinklingnozzle will be automatically shifted back, so that the water will again be discharged into channel N, thereby causing the backward and forward movement of the sprinkling-nozzle from one end of the frame to the other end thereof.

- -To the supporting-bar is pivoted a spreaderoperating lever U, the inner end U of which is slidably'secured to the other portion thereof, as shown in Fig. 1. The inner end of the member U of this lever is pivotal-lysecuredto the collar 0 of the rod 0. To the supportingbar are rigidly secured shifting-arms V, the lower ends of which are bifurcated and straddle the screw-threaded rod W, which is rigidly secured to a U-shaped cross-arm X, which is rigidly secured to the top ofthe standard at the left-hand side of the machine. Between the shifting-arms on this screw-threaded rod is the internally-screw-threaded ratchetwheel Y, having in the periphery thereof oppositelypointed teeth Y and Y. (Most clearly shown in Fig. 5.) Pivotally secured to the outer end of the spreader-operating lever are dogs Z and Z. To these dogs are secured the spring a, which cause the free ends of the dogs to engage the ratchet-wheel. These dogs near their attachment to the lever are provided with notches Z) for the reception of the free end of the bar 0, which is pivoted to the same lever as the When the bar 0 engages the notch in the dog Z, as shown in Fig. 1, the dog is held out of engagement with the ratchetwheel and the dog Z is brought into engagement therewith, and as the bar O oscillates the ratchet-wheel is caused to travel on the rod W, thereby causing the supporting-bar E to be gradually turned. It will be understood that at the beginning of the operation, however, the supporting-bar and the deliverynozzle are in the position shown in Fig. 3 and that when the ratchet-wheel has made its complete travel on the rod W the sprinkling and delivery nozzle will be on the right-hand side of the frame at the same elevation as is shown to the left inFig. 3. Just before the extreme limit of movement is reached by the ratchet-wheel the shifting-arm contacts with the end of the rocking lever cl, which lever is pivoted to the cross-arm X, as shown most clearly in Fig. 1. This rocking lever is provided near one end with a catch 03', which' bends outwardly and then inwardly and is adaptedto engage a pin 6, which is mounted in .the top of the tripping-lever g, which is pivoted to the cross-bar by a small bolt 71, as best shown in Figs. 1 and 3. To the top of this lever is secured aspring z, the

other end of which is secured to the cross-bar X. On the lower end of this lever are studs which provide means for attaching a small pin on the upper end of the tripping-lever, thereby permitting the spring attached to theupper end thereof through the wire cord to release the catch K from engagement with the handle J of the hydrant, thereby permitting the hydrant to automatically close. When it is desired to start the sprinkler again, it is moved to a new place, the dog Z is thrown into engagement with the ratchet-wheel, and the dog Z is locked out of engagement with the ratchet-wheel. The hydrant is locked open, as shown in Fig. 4. The wire cord is drawn taut, as shown in Figs. 3 and 4, and secured to the tripping-lever, which is fastened in the position shown in Fig. 3, as hereinbeforedescribed. A reel Z is provided on the base of the frame to take up the slack, if any, in the cord is, or to pay out more cord, if desired.

It willthusbe seen that my improved sprinkling-nozzle will automatically work itself from a position nearly horizontal on one side of the frame to a like position nearly horizontal on the other side of the frame and that it also moves automatically backwa'rd and forward from one end to the other end of the frame as it travels from one side of the frame to the other. The width of the strip of lawn that is sprinkled thereby is regulated within certain limits by the position of the stops T.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is
